This release includes a change to the
HttpURLConnection instrumentation that creates a
TimerTask to help ensure complete externals reporting. Under some circumstances this may result in a large number of threads being created, which may exhaust the maximum allocated to the JVM, causing it to stop. This issue has been fixed in the 8.0.1 release and it's highly recommended that you update to this version of the Java agent.

The following previously deprecated instrumentation modules were removed:
The previously deprecated
response.statusMessage transaction/span attributes were removed. These have been replaced by
http.statusText. If you've any custom dashboards or alerts that query the
response.statusMessage attributes then they will need to be updated to instead use
Update to latest version
To identify which version of the Java agent you're currently using, run
java -jar newrelic.jar -v. Your Java agent version will be printed to your console.
Then, to update to the latest Java agent version:
- Back up the entire Java agent root directory to another location. Rename that directory to
#.#.#is the agent version number.
- Download the agent.
- Unzip the new agent download file, then copy
newrelic.jarinto the original Java agent root directory.
- Compare your old
newrelic.ymlwith the newly downloaded
newrelic.ymlfrom the zip, and update the file if needed.
- Restart your Java dispatcher.
If you experience issues after the Java agent update, restore from the backed-up New Relic agent directory.
Update agent config differences
We add new settings to
newrelic.yml as we release new versions of the agent. You can use
diff or another diffing utility to see what's changed, and add the new config settings to your old file. Make sure not to overwrite any customizations you've made to the file, such as your license key, app name, or changes to default settings.
For example, if you
diff the default
newrelic.yml files for Java agent versions 7.10.0 and 7.11.0, the results printed to the console will be like:
➜ diff newrelic_7.10.0.yml newrelic_7.11.0.yml...107a108,119> # Whether the log events should include context from loggers with support for that.> include_context_data:>> # When true, application logs will contain context data.> enabled: false>> # A comma separated list of attribute keys whose values should be sent to New Relic.> #include:>> # A comma separated list of attribute keys whose values should not be sent to New Relic.> #exclude:>125a138>128c141< enabled: false---> enabled: true...
In this example, these lines were added to the default
newrelic.yml in Java agent version 7.11.0. If you're moving to 7.11.0 or higher, you should add these new lines to your original
